Hi guys.
Does anybody know how can I reset the the black developing Unit image chipset. I bought the chipset but I don't know the instruction.
Thank you.

Why would you want to reset the dev unit counter?

You can simply disable the message in CE mode for free with the need for a chip!

cause I've done this procedure before on c652 but i couldnt do it on this type.
Generally it is the matter of curiousity rather than need.
anyway do you know how it is possible?
just some general information would be helpful

those machines change bias voltages as they wear, if you replace the chip with old developer unit it can mess with the color dramatically.
best to just turn off the message.
